I'm not getting any sound when playing DVDs with Windows Media Player. I've also tried two other DVD players and no sound there either. I can play an audio CD with Windows Media Player, and sound is fine in games, event sounds, etc. but for some odd reason I don't get any sound when playing DVD movies. I've searched through all the entries here and at "Ask Dave" and everything checks out fine. I've reinstalled the latest driver 3 times on my HT Omega Striker, I've checked all the WMP settings, device settings, Windows device settings, driver is enabled, directx is updated, everything -- still no sound for DVDs in Windows XP. When I boot to my Windows 7 partition everything works fine, but not in my main Windows XP partition. Any ideas?
